ChatDOC

ChatDOC organizes workflows around reading, Q&A, and information verification, starting from document uploads. Its TapSource references can link back to the relevant content via footnotes, data, and selected text, making it easy to review the basis for answers and their context.

The official platform showcases formulas, images, and cross-page table handling, while also offering document translation, a prompt library, and multi-file reading capabilities. The public access portal lists formats such as PDF, Word, scanned documents, web pages, EPUB, Markdown, and plain text; for details on supported account types, please refer to the relevant plan.

The quotas for different file formats, OCR, translation, and image analysis vary; image analysis is listed as a paid add-on. Before uploading, ensure that your materials are eligible for this service. Even after completing responses and translations, you must still cross-check key facts and tables against the original text—do not treat marketing claims such as “format preservation” as an absolute guarantee for all files.
